阅读更多关于 Elastic Beanstalk URL root not working - EC2 Elastic IP and Elastic IP Public DNS working

问题 I am trying to deploy a Django app (1.11.3) to elastic beanstalk (Python 3.4). My issue is that my root route is not working correctly when I use the elastic beanstalk url, but works correctly when using the EC2 Elastic IP or EC2 Elastic IP Public DNS address. When trying to view the root route of the elastic beanstalk url, the page never loads and ends with chrome showing ERR_CONNECTION_TIMED_OUT. All other routes other than the route route (/members, /contact, etc) are working correctly

阅读更多关于 how to have Azure blob storage files be reachable via custom domain redirect or rewrite without resulting in browser security alerts?

问题 This is a follow up to my question from yesterday Azure Storage blob using custom domain is not resolving while subdomain worked - how to set up host records? The objective is to have blob storage files be reachable and ranked on google via our custom domain for example: http://contoso.com/docs/product1-specs.pdf. This is a new website and so there's no concern with needed redirects from old links. so in an html file on "contoso.com/product1" you'd have an internal link for example <a href="

问题 I switched my app's domain, and the redirect works for urls that use http, but I have some links lurking around on the web using HTTPS that aren't redirecting.

However, I want to be moving on, because the address verification letter from Google may take several weeks. So, I would like to put in the domain that I think that I'm going to use. Can I do that, even though I don't own it (yet)? Do they check if it's registered? Or are they just saying that it won't work because I can't
